Lohan must return to Sautner’s courtroom on February 22 for another progress report.

If she completes the remaining 29 days of community service work at the morgue by a March 29 hearing, it could be the end of her supervised probation.

If she fails, she could spend months in a jail, the judge has told her.

Lohan stumbled in November when she was found in violation of her probation. She admitted that she failed to comply with Sautner’s earlier order that she work at a women’s shelter. Her punishment — a 30-day jail sentence — translated into just a few hours behind bars because of measures to reduce overcrowding in Los Angeles County jails.

The court-ordered community service is part of Lohan’s sentence imposed in May when she pleaded guilty to stealing a necklace from a Venice, California, jewelry store.

Lohan was already on probation for two drunken driving convictions from 2007.

Her legal woes have been compounded by her failure to attend counseling classes and alcohol and drug test failures in the past.
